Electric Powersteering Conversion Fail

[Quadcammer]

Howdy all,
I know a few people have converted to electric powersteering setups on their track car and seemingly have no issues. Given my luck, it seems like I'm one of the few to have an issue.

Setup
TRW pump from Opel/Vauxhall that supposedly was reman'ed. Not sure about quality of reman as was done in poland.
Russell 6-an powersteering line for both pressure and return
rebel racing rack fittings
Pentosin CHF 202 fluid
80 amp resettable breaker on power wire
986 boxster on NT01s so hardly a cup car on slicks

Issue:
On certain high G turns, steering gets heavy and then slowly returns. On some occasions, the pump will trip the breaker and will lose PS for the session. Examples include turns 8 and 9 at Thunderbolt (octopus) and Chute/Toe of the boot at WGI.

Any ideas on what I should check or consider? I'd be happy to rebuild the pump again, but I don't see any rebuild kits, making me wonder what was reman'ed in poland anyway.

Now some people will say that cup car pump and the TRW pump from pedestrian cars are different, but I haven't seen any evidence of that.

Anyway, any assistance would be helpful.

Thanks.
